Prior to 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5, MapFish Print accepts an attacker-controlled GML layer url in requests to the /api/print3/print endpoint and fetches XML parsed by core/src/main/java/org/mapfish/print/map/geotools/GmlLayer.java without disabling external entities and external DTDs. A remote XML document and DTD can expand a local file entity, and the resulting content can be exposed through the GML parsing and error path. This allows unauthenticated attackers to read files such as operating-system account data, Kubernetes service-account tokens, and certificates. Replacing the file entity target with an internal HTTP endpoint also permits server-side request forgery. This issue is fixed in versions 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5. ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Package advisory (CVE-2026-55848) Affected packages: - `org.mapfish.print:print-lib >= 3.0.0, < 3.28.30` - `org.mapfish:print.print-servlet >= 3.0.0, < 3.28.30` - `org.mapfish.print:print-lib >= 3.29.0, < 3.30.32` - `org.mapfish.print:print-servlet >= 3.29.0, < 3.30.32` - `org.mapfish.print:print-servlet >= 3.31.0, < 3.31.24` - `org.mapfish.print:print-lib >= 3.32.0, < 3.33.16` - `org.mapfish.print:print-servlet >= 3.32.0, < 3.33.16` - `org.mapfish.print:print-lib >= 3.34.0, < 4.0.5` - `org.mapfish.print:print-servlet >= 3.34.0, < 4.0.5` Patched in: - `org.mapfish.print:print-lib 3.28.30` - `org.mapfish:print.print-servlet 3.28.30` - `org.mapfish.print:print-lib 3.30.32` - `org.mapfish.print:print-servlet 3.30.32` - `org.mapfish.print:print-servlet 3.31.24` - `org.mapfish.print:print-lib 3.33.16` - `org.mapfish.print:print-servlet 3.33.16` - `org.mapfish.print:print-lib 4.0.5` - `org.mapfish.print:print-servlet 4.0.5` Source: https://github.com/advisories/GHSA-5v29-34h8-v68r
